7.
Pull the black or color head toward you and disconnect the head flexible flat cable (FFC) on the head
driver board (nozzle selector). Then remove the black or color head.
CAUTION
r Take proper measures to protect the printhead unit from static electricity, because the driver IC
is directly attached to the printhead unit.
r
Never touch the metallic nozzle surface cover of the printhead. Handle it only by holding the
edges of the printhead.
r When the printhead or the printer mechanism is replaced, the block resistor must be replaced at
location RM4 (for Normal Dot R), RM5(for Micro Dot M), RM11 (for Normal Dot R), and RM12
(for Micro Dot M) on the C164 MAIN Board. (Every spare printhead or spare printer mechanism
comes with a block resistor that is specifically selected for each printhead. And the resistance
value of block resistor are written on the nozzle face of printhead. (Refer to Figure 3-10.)
